Abstract: We establish long-time existence and exponential convergence of a particularly chosen curvature flows, with a coordinate sphere of large radius serving as the initial surface. The limit surfaces form a foliation of the underlying space outside a large ball. Finally, we utilize this foliation to define a center of mass, proving that it agrees with the one defined by Huisken-Yau.
